摘要为了研究空泡溃灭后残余气泡对压力容器钢的腐蚀行为（区别于空泡冲击引起的腐蚀），测定了空泡作用下残余气泡对压力容器钢的腐蚀电位和空泡作用下Pt的开路电位。腐蚀试样的表面也进行了研究，使用X射线光电子能谱。结果表明，残余气泡的Pt电极的电位移动到一个更阳极电位和由残余气泡引起的氧化层是从正常的水没有残余气泡产生的不同。
Abstract The corrosion potential of pressure vessel steel after exposure to residual bubbles and the open-circuit potential of Pt during cavitation were measured to investigate the corrosion behavior induced by residual bubbles after cavitation bubble collapse (as distinct from erosion caused by cavitation impact). The surfaces of the corrosion specimens were also investigated using x-ray photoelectron spectroscopy. It was shown that the residual bubbles shift the potential of a Pt electrode to a more anodic potential and that the oxide layer induced by the residual bubbles is different from that produced by normal water without residual bubbles.
